截止阀标准一览

截止阀标准一览 2011： 截止阀的启闭件是塞形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动。阀杆的运动形式，有升降杆式（阀杆升降，手轮不升降），也有升降旋转杆式（手轮与阀杆一起旋转升降，螺母设在阀体上）。截止阀只适用于全开和全关，不允许作调节和节流。截止阀属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不泄漏。当介质由阀瓣下方进入阀六时，操作力所需要克服的阻力，是阀杆和填料的磨擦力与由介质的压力所产生的推力，关阀门的力比开阀门的力大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。近年来，从自密封的阀门出现后，截止阀的介质流向就改由阀瓣上方进入阀腔，这时在介质压力作用下，关阀门的力小，而开阀门的力大，阀杆的直径可以相应地减少。同时，在介质作用下，这种形式的阀门也较严密。我国阀门“三化给”曾规定，截止阀的流向，一律采用自上而下。截止阀开启时，阀瓣的开启高度，为公称直径的25%～30%时，流量已达到最大，表示阀门已达全开位置。所以截止阀的全开位置，应由阀瓣的行程来决定。标准编号标准中文名称标准英文名称DL/T531-1994(2005复审) 电站高温高压截止阀、闸阀技术条件GB/T11689-1989 船用法兰铸钢截止阀(四进位)Marine cast steel flanged stop valvesGB/T12235-1989 通用阀门法兰连接钢制截止阀和升降式止回阀General purpose industrial valves—Flanged steel globe valves and lift check valvesGB/T12233-1989 通用阀门铁制截止阀与升降式止回阀General purpose industrial valves—Casting iron globe valves and lift check valvesGB/T1951-1984 船用低压外螺纹青铜截止阀Marine low pressure bronze male threaded stop valvesGB/T2499-1993 船用法兰铸铁双排截止阀箱Marine cast iron flange dual-row stop valves-caseGB/T590-1993 船用法兰铸铁截止阀Marine cast iron flanged stop valvesGB/T594-1983 船用外螺纹锻钢截止阀Marine forged steel male thread stop valvesGB/T584-1999 船用法兰铸钢截止阀Marine cast steel flanged stop valvesGB/T595-1983 船用外螺纹青铜截止阀Marine bronze male thread stop valvesGB/T587-1993 船用法兰青铜截止阀Marine bronze flanged stop valvesJB/T7245-1994 制冷装置用截止阀JB/T7747-1995 针形截止阀JB/T9081-1999 空气分离设备用低温截止阀和节流阀技术条件JB/T53165-1999 高压平衡截止阀 产品质量分等JB/T53174-1999 截止阀产品质量分等JB/T53155-1999 空气分离设备用低温截止阀和节流阀 产品质量分等JB/T8859-2004 截止阀静压寿命试验规程HG/T3215-1986 聚三氟氯乙烯塑料衬里截止阀NF E29-350-2003 工业用阀.钢制球阀、球状截止阀和止回阀(Industrial valves - Steel globe and globe stop and check valves.)NF P43-001-2000 建筑物用阀门.建筑物中供应引用水用铜合金截止阀.试验和要求(Building valves - Copper alloy stopvalves for potable water supply in buildings - Tests and requirements.)NF D36-380-2001 燃气燃烧器和燃气用具用自动截止阀的阀门检验系统(Valve proving systems for automatic shut-off valves for gas burners and gas appliances.)NF A84-621-2002 气焊设备.焊接、切割和相关工艺用带截止阀的速动连接(Gas welding equipment - Quick-action coupling with shut-off valves for welding, cutting and allied processes.)NF M88-771-1975 液化烃容器装置.手动截止阀.制造.功能.试验(LIQUEFIED HYDROCARBON INSTALLATIONS IN CONTAINERS.
